IMPRO'VED LUBRICATOR.

The Schedule referred to :ln these Letters' Patent and making part of the same.

To all 'whom it 'may concern clared to be a correct description of the same.

In thejlnbricators heretofore made a screw stopper l ;.sheen provided within a cap that is attached by a Vbayonet joint. This is very dificult to handle in the heated state, because the entire cap has to be grasped and the steam confined in the cap often escapes suddenly as the cap is removed, blowing lthe heated grease upon -the person.

In inyimproved oil-cup the cap is provided with a wooden or non-conducting handle, and screws upon the cup,and within the cap there is a stopper 'set upou a vertical spindle, so that the stopper remains stationary upon its seat as the cap is screwed up tightly; an annular cavity around the mouth of the oil-cup receives a ring of the Jenkins compressible packing that forms a seat for the stopper, and an escapehole is made through the side ot' the cap, so that confined steam passes olf freely as the cap is removed, andthe entire cap and stopper are removed or replaced simply through the agency of the non-conducting handle.

In the drawing- Figure 1 is a vertical'section of the luhricator complete.

Figure 2 shows the top of the cup with the cap partiaily removed.

The cup a is provided with a stern, b, valve c, and connection d for a' steam-chest, or other article to whichV it is to be attached. These parts are to be of any desired size or shape .and form no part of my iuvention.

Around the upper end of the cup a, a screw-thread is provided for the cap c,v and f is a wooden or other non-conducting handle passing through the head of the cap. f

-The stopperA h is mounted upon a spindle, i, passing through the cap c and handle f, and k is a nut, rctaining the same, but allowing t-he stopper and its spindle to turn freely in the cap, so that the said stopper h may remain stationary upon its seat o while-the cap e is screwed down to place; thereby the stopper does not have to turn around upon its seat;

The seat o is made of a ring of the compressible packing known as the Jenkins packing, patented May s, 1866.

I form an annular recess for this packing by the anges fr s extending inward' from the rim ot' the oilcup a.

The hole n is provided through one side of the cap e, so that when the cap is loosened the confined steam will escape, as indicated in fig. 2.

I claim as my inventionl. rIhe nonlconducting handle j, passing transversely through the cap e, and through which handle the spindle e' of the stopper h passes, in combination with the oil-cup a, as and for the pprposes speciled.

2. rI he escape-hole n, introduced in the screwcap e f the oil'cup a, for the purposes and as set forth.

Dated December 22, 1869.
